Magma

Description:
Online video aggregator and social networking tool that allows the user to view videos from various sources (e.g., YouTube, Vimeo, Hulu), view the latest in viral videos and memes, tailor recommendations to your interests, create libraries of your favorite videos, submit videos that aren't already in Magma's collection, and swap video recommendation with your friends all in one site. You can also upload videos of your own and track what people are saying about them online: everything from formal reviews in e-magazines to social bookmarking sites to passing comments on Twitter.
